My invention relates to a shaving implement adapted for use as a dryshaver of the motor driven type.

Among the objects of my invention are to pro- 5 vide a shaving implementadapted to give to the user a very close shave; to provide a shavingimplement having a combined guard and guide member for positioning theshaving implement on the users face at the proper angle for a closeshave and also preventing the implement from cutting the face of theuser and at the same time protecting the implement from injury; tocreate a shaving implement having resilient means for permitting theinner comb to reciprocate against the stationary comb without frictionbetween the reciprocating comb and the resilient member, said resilientmember surrounding the driving shaft so as to prevent chattering and toinsure an evenly directed pressure on the reciprocating comb; to createa shaving implement which is substantially non-clogging, its parts beingso arranged that there are no portions for the retention of clippedhair; to supply a shaving implement more simple in construction andeconomical of manufacture, and such other objects, advantages andcapabilities as will later more fully appear and which are inherentlypossessed by my invention.

While I have shown in the accompanying drawing a preferred embodiment ofmy invention, yet I Wish it understood that the same is susceptible ofmodification and change without departing from the spirit of myinvention.

Fig. 1 is a perspective view of my shaving implement with a` portionbroken away to show the motor; Fig. 2 is a front view of the head of myshaving implement with the retaining plate partly broken away andshowing the top portion kof the driving mechanism; Fig. 3 is a side viewof the structure shown-in Fig. 2; Fig. 4 is a plan detail 40 view, andFig. 5 is a side view of my spring retaining hearing or button. Fig. 6is a front detail view of my inner reciprocating comb and Fig. '7 is aside view of the same.

The implement selected to illustrate my invention comprises a hollowhandle Il! in which is arranged in any suitable manner an electric motorI I adapted to be connected to an electrical source of supply by leadwires l2. The motor II has a driving shaft 'I3 ending in an eccentric I4adapted to engage a head I5.

My head I5 comprises a base i5 to which is attached by suitable meanssuch as screws I l, an cuter angle plate i8, the shorter bent portion ofwhich forms a `stationary comb i9. An inner a le plate 2@ is positionedwithin the interior portion of the outer angle plate I8, the shorterbent portion of said inner angle plate 20 forming a reciprocating comb2|. A resilient member 22 has one end seated in a reess-23 in the baseI6. The other end of the resilient member 22 engages 5 a recess 24 in abutton.9 rsprihg retaining bearing 25. Said button 25 has thrustbearings 26 adapted to lie against a pair of lugs 21, said lugs 2lformed from a cutout portion 28 in portion 29 of inner angle plate 20.Said button 25 also has a 10 hub 30 adaptedto t between said lugs 21 forimparting reciprocating movement to the reciprocating comb 2|.

A retaining plate 3l has one end attached by suitable means such asscrews 32 to the base I6 l5,

and has a portion 33 bent at a right angle to bear against the innerangle plate 20 to hold the inner angle plate 20 against the outer angleplate I 8, and for sealing the moving' mechanism so that it is protectedfrom cut hair. cuticle matter or 20 the like.

The outer angle plate I8 has a comb I9, the teeth 34 of which formparallel cutting edges 35. 'Ihe comb I9 remains in a stationaryposition.

In the" comb 2I which lies against the inner side 25 of thestationarycomb I9, the teeth 36 form parallel cutting edges 3l. Said inner comb 2Iis adapted to be moved in a reciprocating movement through the followingconstruction: The driving shaft I3 passes through an aperture 38 in thebase 30 I6 and extends so that the eccentricv I4 is engaged in anelongated pocket 39 in button 25. As the eccentric I4 is actuated andmoves the button 25, the hub 30 of the button moves the inner c'omb 2lin a reciprocating movement across the inner 35 surface of the outercomb I9.

The outer comb I9 is knife blade or wedge shaped in that it tapers to anextremely thin front edge 40. The comb I9 having such a thin edge,permits the user to obtain a shave at least 40 as close a's theinfinitesimal thickness of said thin edge. Because the comb I9 is sothin at its maximum close shaving contact position, it is desirable forgeneral use to employ a guard guide 4I which I provide in the shape of asubstantially U-shaped member, the ends 42 of which removably andfrictionally fit into apertures 43 in oppositely disposed sides of thebase I6. The connecting portion 44 of the U-shaped guard guide is spacedfrom the edges of the combs so that a user is guided into a position fora correct close shave and at the same time is guarded against dangerfrom cutting due to too close a shave. 'Ihe guard guide also protectsthe combs from injury. 5e

The inner exposed face 45 of my reciprocating comb 2I permits the freeand immediate escape of cut hair'. My head l5 is so constructed that ithas open front and sides adjacent the inner exposed face 45 of myreciprocating comb 2 I.

' There are no pockets into which cut hair may accumulate to clog andeven stall working parts. My head vhaving no such pockets, needs noextraneous cleaning devices for the removal of cut kgreater -thanthestroke of the reciprocating comb v 2l so that the resilient member 22may oscillate free from contactv with the driving shaft I3. My

resilient member 22 engaging the recess 24 of the button 25 is capableof lateral as Well as thrust movement, thus eliminating 4any frictionalcontacts.

In operation the-'hair of a person shaving enters the slots 46 of combI9 and the slots 41 of comb 2 I,

and are clip ed by the reciprocating action of the inner comb 2| againstthe outer comb I9.

Having thus described my invention, I claim:

l. A shaving implement comprising a base, a stationary comb attached tosaid base, a movable comb positioned against said stationary comb, saidmovable comb having an inner exposed face so as to permit free escape ofcut hair, means for reciprocating said movable comb so that the teeth ofsaid movable comb operate transversely to the openings in the stationarycomb, and a re taining plate attached to said base on one end,
